URL: https://github.com/apache/shardingsphere/issues/14163


   Hi community,
   
   At present, DistSQL can manage sharding, readwrite-splitting and other 
feature rules, but it has not yet provided support for global rules (authority 
and transaction).
   So I suggest to add a syntax to query authority rule: `SHOW AUTHORITY RULE`.
   
   And the content of authority rule should includes users and provider 
information:
   #### ALL_PRIVILEGES_PERMITTED
   ```yaml
   - !AUTHORITY
       users:
         - root@%:root
         - sharding@:sharding
       provider:
         type: ALL_PRIVILEGES_PERMITTED
   ```
   #### SCHEMA_PRIVILEGES_PERMITTED
   ```yaml
     - !AUTHORITY
       users:
         - root@:root
         - user1@:user1
         - [email protected]:user1
       provider:
         type: SCHEMA_PRIVILEGES_PERMITTED
         props: 
           user-schema-mappings: root@=test, [email protected]=db_dal_admin, 
user1@=test, user1@=db_dal_admin
   ```
   
   
   ### Reference
   
   `show sharding algorithms` is a good reference:
